The invention discloses a hydrogen utilization device of a hydrogen fuel cell vehicle. The hydrogen utilization device comprises a heat-insulating shell, a porous heat conduction metal layer and a catalytic layer, one end of the heat-insulating shell is open; the porous heat-conducting metal layer is mounted at the opening of the heat-insulating shell, and through holes in the porous heat-conducting metal layer are used for enabling hydrogen leaked by the hydrogen fuel cell vehicle to enter the heat-insulating shell; the porous heat-conducting metal layer is used for being close to or coatinga hydrogen storage bottle of the hydrogen fuel cell vehicle; the catalytic layer is installed in the heat-insulating shell and used for catalyzing hydrogen entering the heat-insulating shell to be combusted. The catalytic layer is arranged in the hydrogen utilization device, hydrogen leaked in the normal operation process of the hydrogen fuel cell vehicle can be subjected to catalytic combustion,the hydrogen storage bottle is heated, the explosion lower limit that the concentration of the hydrogen exceeds 4% is avoided, the safety risk is reduced, and the hydrogen utilization rate is increased. The invention further provides a hydrogen utilization method of the hydrogen fuel cell vehicle.
